Field of the Invention The present invention relates to a method of driving a data line, and more particularly to a driving method for driving a liquid crystal display line in a disturbing driving manner. [Prior Art] The rapid advancement of the multimedia society has largely benefited from the dramatic advancement of semiconductor components or human-machine display devices. In terms of displays, cathode ray tubes (CRTs) have always dominated the display market in recent years due to their excellent display quality and economics. However, for an environment where individuals operate multiple terminal/display devices simultaneously on the table, or from an environmentally friendly point of view, if there is a trend to save energy, cathode ray tubes still have many problems due to space utilization and energy consumption. However, the demand for light, thin, short, small and low power consumption cannot effectively provide a solution. Therefore, a thin film transistor liquid crystal display (TFT LCD) having superior properties such as high enamel quality, good space utilization efficiency, low power consumption, and no radiation has gradually become the mainstream of the market.
